Assuming that one is a fan of the sort of abstract computer-scientific approach to programming embodied by Lisp (and I am!), then it should be a good thing when people discover it.

Is there a benefit in spreading this discovery to others, even after it's been known so long? Certainly I think so; it's new to everyone at some point, and, since I wasn't originally motivated to read McCarthy's original papers, I wouldn't have discovered the ideas of Lisp without recent expositions of it. Granting the benefit of this, who can better communicate with the unenlightened, in terms familiar to them, than a recent convert? (Although, as braythwayt points out (https://news.ycombinator.com/item?id=9641279), he is scarcely a newcomer to the party.)
